LOCKING-PLATE. FOR TABLE-LEGS.

.QJECIFICATION forming part of Letters Patent No. 323,582, dated August 4, 1885.

Application filed March 11, 1885. (No model.)

has for its object to provide for detachably connecting the table-legs with the table proper. In the accompanying drawings, forming a part of this specification, and on which simi-.

lar letters of reference indicate the same or corresponding; features, Figure 1 represents a perspective view of a portion of a table and the table-leg, showing the locking-plate partly fitted into position; Fig. 2, a detached inverted sectional view of aportion of the table,showin g the manner of connecting the locking-plate therewith; Fig. 3, a plan view of the upper end of the leg; Fig. at, a detached inverted view showing a modified manner of constructing the rails, and Fig. 5 a like view to Fig. 3, showing a modified form of the construction of theleg.

The letter A designates the table-top, to which are connected in any approved manner the several rails, B-in the present instance by recessing the inner sides of the rails at intervals and entering screws through the rails upwardly and into the table-top, as seen in Fig. 2. The rails do not meet each other at the corners, but approach each other just close enough to allow room for the intervention of the leg, as will presently appear. The inner sides of the rails B are provided with vertical kerfs or incisions B.

The letter C designates the lockingplate, which is preferably constructed of sheet metal, though it may be cast. It consists of the wings D and E, standing preferably at right angles and having flanges F formed at the edge of either wing,whi-ch fit into the kerfs B. Each wing is also provided with a number of apertures, through which pass the connectingscrews G, which, together with the flanges and kerfs, eifect a strong connection between the wings of the locking-plate and the rails.

At the corner or angle of the plate where the two wings meet are provided projecting lugs H, the lugs which project in line with the wing E being cut from the body of the wing D, and those from the wing D being cut from the body of the wing E, in case the locking-plate is formed of sheet metal. This construction economizes in the consumption of metal, for if the plate were made of cast metal the lugs would be so much additional material in each plate. W'e would have it understood, however, that the plates may be cast. These lugs form avery important and material feature of 'ourinvention, as we shall presently point out. The upper ends of the legs Iare provided with vertical slots K, disposed relatively to each other to correspond with the relative position of the wings D and E of the lockingplate, and are extended beyond each other at the point of intersection. The longer portions of these kerfs J receive, respectively, the wingsD and E, while the extended portions receive the lugs H. By this means it will be observed that not only the inner corner or portion, K", of the leg is depended upon to connect it with the table proper, but that in addition to this portion that part of each leg designated by the letter L will also be connected with the table, the lugs H being the means of accon1- plishing this additional connection. From this it follows that the strength of the portion K is not merely depended upon, but that the strength of the remaining portions L of the leg is also utilized, effecting a union between the leg and table proper.

As seen in Figs. 4 and 5, the railsB are provided with short tenons b, which extend into corresponding mortises, c, in the upper ends of the legs. This provision affords additional strength to the connection between the legs and table proper, but may or may not be used.

We do not contemplate the use of glue in fastening the legs to the table proper, as, owing to the construction of our lockingplate, such is not necessary; and, further, the use of glue would nullify the detachability of the. legs. Should, however, it be desired to permanently connect the legs with the table, a coating of glue may be applied to the ends of the rails and to the tenons and mortises shown in Figs. 4 and The detachability of the legs allows of their removal, so as to be compaetl y shipped with the table proper.

We desire to observe that we are aware that a clamp has been made which partly embraces the exterior of the table-leg and has short projecting flanges at its ends which enter the table-rails, and others at intermediate points which enter slightly into the leg. The difi'erence between such device and ours is most apparent, since the body of our locking-plate passes through the leg and not around it, and has lugs disposed at an angle to each other and extended in both directions beyond the angle of the plate. The advantage of this construction is fully set forth above in speaking of how the lugs form a connection with the outer portion, L, of the post. This is a material feature, and is not possessed by the device alluded to.

Having thus fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

lugs at the angle of the plate formed from the A body thereof, and which extend each beyond the other.

In testimony whereof we affix our signatures in presence of two witnesses.
